Abstract (en)
[origin: WO9514881A1] A vacuum heat insulating material (6) formed by packaging tightly under vacuum a molded body (1), which comprises needle crystals of calcium silicate combined three-dimensionally, in containers (2, 3, 4) of a compound film formed by laminating metal foil on a plastic film or vapor depositing a metal or metal oxide on such a film, the heat conductivity of this material 6 at 20 DEG C being not higher than 0.015 Kcal/m hr DEG C. This vacuum heat insulating material (6) does not cause environmental problems concerning the generation of dust when it is thrown away, and, moreover, it displays excellent heat insulating performance without using CFCs.
